I'm not real knowledgeable about BK radios. I have a set of four of the PRC127 military issue VHF HTs complete with programming cable and the field programming module, but no real info to work from. Anyone know where I might find some service documentation on line or in print? Is BK / Relm weird about software like Motherola is? Is software for these old radios available anywhere?

I had already been to RBTIPs page, and some of the links were helpful. Sadly, the links to the Communications Repair Depot (wildlandradios.com) do not seem to work any more. I think I have some of the documentation I need, but I'm still wondering about the software. If asking about software is a bad thing to do at this board I won't push it, though.

PRC127's should not need programming software. Press and hold the F key until the display says "ch 0". Enter the channel # you want to program then press F again to cycle through the following. Sequence is rx freq, rx tone, tx freq, tx tone. When done, turn the radio off then on. It should be good to go.
Have fun.
